Game machine, game machine system, and method of controlling a game machine reel spin time

摘要

A game machine includes a monitor, a comparator and an adjuster. The monitor monitors a difference between the amount of game value inserted and the amount of game value paid. The comparator compares the difference with a preset reference value. The adjuster extends a game time of a game performed on the monitor when a result of the comparison that the difference is greater than the reference value is determined by the comparator.
